Neutron reflectometry gives information (depth-dependent composition) on the structure of thin films and surfaces which can be solid/solid, solid/liquid, liquid/liquid and liquid/air interfaces. There are 3 dedicated reflectometry instruments and a fourth instrument (D16) can also be used. The instruments are optimized for different kinds of scientific studies, for example liquid/liquid and liquid/air interfaces on FIGARO and magnetic structures on D17 and SuperAdam. Contrast variation based on isotopic substitution (normally hydrogen → deuterium) is widely used in soft matter and biology studies, typically on D16, D17 and FIGARO – support can be provided for deuteration.
An overview of instrument parameters is provided in the table below to help you choose the most suitable instrument. By clicking on the instrument, you can go directly to the dedicated instrument pages where more information can be found, including scientific highlights and contact details for the instrument scientists.
